TORO Quick Link Automatic Sprinkler Valve (Jar Top) not working?

Question

I have checked this and ensured that the flow control is turned on. I have also found that:

1. Valve works in manual mode

2. Solenoid is getting electricity and water seems to be flowing in automatic mode but nothing is coming out of the sprinkler.

I am not sure what could be broken as manual operation works and solenoid sems to be working. Any ideas?

Thanks.

Answer 1

Okay Sam, since your valve works in the manual mode then we can assume that there aren't any leaks downstream of the valve.

You say that "water seems to be flowing in the automatic mode but not coming out of the sprinkler."  That is interesting, because if the water if flowing, then it has to go to the sprinklers just as it does when the valve is manually turned on.  I have a feeling that if water is flowing through the valve in your automatic mode, then it is surely going to the sprinklers.  But, if the valve is having a problem and isn't opening up all the way, then your sprinklers will not pop up and the water will just seep out from the heads, given enough time.  This is likely the problem.

And you say that the solenoid is getting voltage, however if the solenoid's seal is physically cracked, torn, or ruptured it could give you problems.  If you have another similar valve that does work, try swapping solenoids.  If the valve then works; replace the solenoid, but if the valve doesn't work then you may have to open up the valve and check for problems, such as a torn valve diaphragm.  Below is a link to a file that shows how to open up and maintain a Toro jar top valve.

One last thought, if the wiring to the valve is borderline bad, your solenoid may not be getting the appropriate needed voltage and current.  Too small of wires, too long of a run, bad or wet connections to the solenoid, all are possible problems that could cause the solenoid not to work, or to weakly latch.  I'm still thinking the first problem, but keep this in mind.

Answer 2

maybe you have a leak past the valve...

do this test,

turn on a valve that works and you can see the sprinklers run,

look and see how fast your water meter is turning while its on

then try it with the zone that is not working.

if it is turning but not as fast, you have an issue with the valve,

if its turning as fast or close to it then you have a leak and need to find it and repair it.

the valve may have trash in it clogging it up.
